Need if regarding world call digital cable tv

friends i need info regarding world call digital box, if i buy any dvb box from market will it work woth my cable tv?

I am not an expert but my understanding is that DVB boxes are for Direct To Home (DTH) satellite television signals (using small dinner plate sized dish antenna), and not for converting digital cable signals for TVs.

Pakistan has not allowed DTH broadcasts yet (PEMRA has solicited bids), so currently no market/use for DVB unless you can catch Indian DVB signals.

You may want to check frequencies used by Worldcall for their cable signals versus frequency tunable by Set Top Box and also type of DVB Pakistan/PEMRA is considering (different countries use different versions).
